An object of the present invention is to provide a laminating-printing system which can further improve the quality of laminated-printed objects. The present invention provides a laminating-printing system including a laminating-printing unit () which prints the layers and sequentially laminates the layers; and a concentration adjusting unit () which adjusts the concentration of gas components in the shield gas, the laminating-printing unit () including: an irradiation section including an irradiation source of energy rays to irradiate the powder material, and a printing section including a chamber filled with the shield gas and a printing stage on which the layers are printed and laminated, and the concentration adjusting unit () including: a purification section which removes a first gas component which is an impurity in the shield gas based on the powder material; and a supply section which supplies a second gas component selected based on the powder material inside of the chamber as needed.

Laminating-printing system and laminating-printing method

An object of the present invention is to provide a method for manufacturing a metal printed object that can reduce the generation of sputters, and the present invention provides a method for manufacturing a metal printed object in which, in the presence of a shielding gas supplied around metal powder in a chamber, heat is supplied to the metal powder using energy rays to form a metal layer and laminate the metal layer, wherein the mass per unit volume of the shielding gas at a temperature of 25° C. and a pressure of 0.1 MPa is 1.30×10g/cmor less.
